IVIPROVEMENT IN COFFEE-ROASTERS.

Mop-.

The Schedule referred to in these Letters Patent and making part uf the Ilma Be it known that I, BENJAMIN K. MALTBY, of Gincinnati, county of Hamilton, and State of Ohio, have invented a new and useful Apparatus for Roasting Goffee, called, from its peculiar structure, the Pendulum Codec-Roaster, and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this speeificatiom'- in Which- Figure I is an exterior perspective view, giving the form and external combination of parts as put to-l gether for use; and

Figure II,an axial perspective section, showing the lower half' of the cylinder, with the internal arrangement, for properly moving the coiee during the roasting-process.

The structure, as shown in Fig. I, consists of a stationary bed, marked A, which holds the cylinder, and is fitted to rest upon a. stove or other heating-appa latus, and an oscillating cylinder, marked C, closed atA the top by the lid L.

In the bottom of this cylinder, as shown in Fig. II, are narrow, upright blades B B B B, arranged so as to form oblique channels through which the coee is forced back and forth by this voscillating motion.

There is a pendulum attached to one gud'geon of the cylinder, marked P, Fig. I, the lower end made heavy to oi'set'the coiee and promote reaction after the cylinder has rolled nearly to a horizontal position.

.The upper end of the pendulum receives the handle or moving-rod H, by which motion is given to the cylinder either by the hand or machinery.

'lhere is also a perpendicular slide at each end of the roaster, marked S, receiving the gudgeon of the cylinder.

In the slide is an oblong slit or mortisc, through which a screw passes, fastening it to the stationary bed.

or lowered to secure an exact fitto the stationary bed in which it oscillatcs.

The whole may be made of cast-iron, copper, sheetiron, or other metal, and the cylinder cast whole or in two pieces.

The advantages ofthe pendulum roaster over all others heretofore invented, is its neatness, ease of operation, adaptation for being moved by machinery or the hand, or by a person sitting at a distance from it.

By the employment of the oscillating motion, fixtures for closing and handling it may be appended without interfering with the fitting of the cylinder to the bed. This motion also forces the coiiee through the abovedescribed oblique channels, so that suitable motion is given to the roasting coffee, thus. obtaining perfect action while beauty of form is secured.

Speciicatiowof Claim.

What I claim as my invention, and desire to secure By means of these slides the cylinder may be raised
